Changelog: restore the 12.1 rework under 5.0.0 after the v4.8.0 merge

The main merge inserted the 4.8.0 section directly beneath the bare 5.0.0
heading, which left 5.0.0 empty and stranded the whole WoW 12.1 rework and its
Known Issues under a 12.0.x stable release. Same collision as the 4.7.4/4.7.5
merge: 5.0.0 carries no content directly under its heading, so a new stable
section slots into the gap with no conflict.

Only the rework and Known Issues move. The two Click Casting improvements stay
under 4.8.0 — that release shipped them. Pure move, no wording changed.
